Answer:
A positive number is obtained
Step-by-step explanation:
[7-(5-6(2)]+4+2
[7-(-1(2)]+4+2
[7- (-2)]+4+2 = [7+2]+4+2
9 + 4 + 2 = 15
Answer:
The value of y by itself in the equation x+2y=10 is
Step-by-step explanation:
Given equation is x+2y=10 -------- (1)
To find y with given equation as below :
Equation (1) implies that x+2y=10
Subtracting the above equation by x we get
x+2y-x=10-x
x-x+2y=10-x
2y=10-x
Dividing by 2 on both sides we get
Therefore the value of y is
Therefore the value of y by itself in the equation x+2y=10 is
Answer:
1 and 3
Step-by-step explanation:
So they asked you to use the quadratic formula. The quadratic formula is x=-b+/-sqrt b^2-4ac/2a.
So your equation is x^2-4x+3.
x^2 is a. -4 is b. and 3 is c.
x=4+/-sqrt (-4)^2-4(1)(3)/2(1).
This will equal 4+/-sqrt16-12/2
It will simplify to 4+/-2/2.
No you have two equations 4+2/2 and 4-2/2.
4+2/2=3.
4-2/2=1.
Your answers are 1 and 3.
Your answer is 3 2/3 ; 11/3
You had to count the number of wholes, 3, then add the thirds which was 2/3. This is because the rectangle is cut into We the, but can be simplified tothirds. Now, in the diagram, 2 out of the 3 rows are colored meaning 2/3 are colired. Thus, 3 wholes are colored and 2/3 . When you add them, you get 3 2/3. To make it improper, simply multiple 3 by the denominator and add the numerator. 3×3+2=11. Oh the. whole thing over 3.
